Hi Follow the Way, I did not watch the Vlog, but Philippians 2:12 has more than one interpretation.
So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; (NASB)
Does this mean do something to achieve salvation in Christ, or sustain it, or does this refer to the facet of our salvation where we earn rewards through good works such that we enter heaven "abundantly."
I think this verse refers to after we are born anew, and became a new creation for good works. We strive to become more Christ-like, and we strive to serve the ministry of Christ as His ambassadors. Our fear and trembling comes from our love and devotion to Christ, such that we are fearful of dishonoring Him.
